Description

[Detailed explanation of the idea] The present invention relates to an analog display device.

2. Description of the Related Art Conventionally, for example, there has been an analog display device using a crystal as shown in FIG.

This displays the display segment corresponding to the smallest unit of the scale.
Each scale was arranged so that it was located at its center, and - a display segment was selected to indicate the scale located at the center.

Therefore, when the minimum unit of display is small and the width of the display segment is narrow, the scale becomes difficult to read.

Therefore, the present invention makes the display easier to read by selecting a plurality of adjacent display segments corresponding to the minimum unit of the scale and indicating the scale at the intermediate position.

An embodiment of the present invention will be described below based on the drawings.

In FIG. 2, display segments S1...Sl. 0 corresponds to the minimum unit 1 of the scale, and by selecting two adjacent display segments, the scale at the intermediate position is indicated.

In FIG. 2, a scale 50 is indicated.

The display segment is formed of one glass substrate (not shown) as shown in FIG.

) provided on the common electrodes C1...C1o and another glass substrate (not shown).

) on the segment electrodes Se...Se, and a liquid crystal filled between both electrodes (not shown).

). Common electrode C1...C□.

Lead wires P, . . . Plo are led out from these, and the segment electrodes Se .

In FIG. 4, A is a pulse generating circuit, and its output terminals a1. a2. From a3, the pulses X in Fig. 5,
W and Y occur.

B and D are the 1st and 1st numerical data to be displayed, respectively.
This is a data generation circuit that generates evening data.

Output terminal block of data generation circuit B... Output is generated when the first position of the data is O...9, and from output terminal d...dlO of the data generation circuit, output is generated as 10 of data.
An output is produced when each m is O...10.

E and F are selection circuits, and selection circuit F selectively generates pulses W and X according to data.

Output terminals f1...fl of the selection circuit E.

are connected to the lead wires P□...Plo, respectively.

G is a determination circuit that determines whether the 10th place of data is an even number or an odd number.

H is a control circuit, and its output terminal...h. are each lead wire q.

...Connected to q9. In the above configuration, the output terminals f1...fl of the selection circuit F.

The data are (0, 1...10) and (10
,11...20)...(90,91...100)
The setting is such that the pulse W is generated when this occurs, and the pulse X is generated at other times.

On the other hand, the output terminal e of the selection circuit E. ...From C9, the first data is (0, 1), (1, 2)... (9)
The setting is such that a pulse W is generated when this happens, and a pulse Y is generated at other times.

In addition, when the data position is the number of corners, the control circuit H is connected to the terminal e.
.

...The output of C9 is connected to each terminal. ... occurs at h9, and conversely, when the number is odd, the outputs of the terminals e, ...eo are generated at the respective terminals h9.

Therefore, when the data is O, the lead line p in FIG.

A pulse W is supplied to tqo, a voltage O is applied to the display segment S1 as shown in FIG. 5, and the liquid crystal becomes non-responsive.

- Thick and thin display segments S2...5100 have pulses Zl, 22. When one of Z3 is applied, the liquid crystal responds.

Therefore, on both sides of the display device of FIG. 2, there are polarizing plates (not shown) whose polarization axes are orthogonal to each other.

), the display segment S1 is bright, the others are dark, and 0 is indicated.

When the data is 1, display segment S1. The applied voltage of S2 becomes O, and the scale 1 at the intermediate position is indicated.

When the data is 2, 3...9, each display segment S2. S3. S3. S...S9. Sl.

The applied voltage becomes O, and each scale is indicated.

When the data is 10, a pulse W is supplied to the common electrodes C1 and C2.

On the other hand, since a pulse W is generated at the terminal h9 of the control circuit H by the output of the discrimination circuit G, the display segments S1o, Sl
, the applied voltage becomes O, and a scale of 10 is indicated.

Data is sent to terminals sequentially up to 11°12-193. h8.
h8. h7...Pulse W is generated at hl and ho, and display segments 5ill s, respectively.

, S12? S13””S19! Each scale is indicated by 320.

Thereafter, in the same manner as above, the scale at the intermediate position is indicated by the two display segments.

Note that in the above embodiment, two display segments are selected and the scale at the intermediate position is specified, but the sixth display segment is not limited to this.
A scale is placed in the center of each display segment as shown in the figure, and 3
Alternatively, one display segment may be selected and a scale at an intermediate position between the two display segments may be selected.

In this case, the display segment is divided into four display segment groups each consisting of, for example, 25 display segments, the segment electrodes of each group are connected in a zigzag manner by 25 lead wires, and a common electrode is provided for each group.

Each group is selected and driven in a time-division manner.

As described above, according to the present invention, since the scale at the intermediate position is indicated by a certain number of two or more display segments, the display is easy to read, and the certain number of display segments are made non-responsive. In order to make the remaining display segments respond, the gap between the above certain number of display segments and this display segment are in the same display state, so that the display segments that indicate the scale appear connected, and the scale is indicated by a single thick display segment. It is displayed as if it had been displayed, making it very easy to see.

Furthermore, there is no crosstalk, and display with good contrast can be performed.
